Abstract

1312709 Method of producing calcium and sodium chlorides E M MITKEVICH V N KOROBANOV V J BABKINA A F SHAKHOVA V N MEFODIEV and N I GAIDASH 14 Nov 1970 54302/70 Heading C1A Calcium and sodium chlorides are produced from the distillation liquid of the ammonia soda ash production process by introduction of purified and solid-free distillation liquid of the process into evaporators 1, 2, 3 of a multipleeffect evaporating plant as indicated by the arrow (a), the evaporators already containing a solution of calcium chloride evaporationconcentrated to 28-45 wt. per cent. Fresh distillation liquid is mixed in each of the evaporators with a concentrated calcium chloride solution. The amount of the fresh distillation liquid introduced into each evaporator is maintained at such a level that the calcium chloride concentration in a mixed solution during the evaporation process be within 28-45 wt per cent. Mixing and evaporation of the liquid result in that sodium chloride, calcium sulphate and calcium hydroxide are precipitated in each of the evaporators. The precipitated substances are continuously taken off the evaporators as a pulp whose liquid phase is essentially a solution of calcium chloride. The sodium chloride is then separated from the pulp mixture.
